REFRIGERATOR CAR AND CHAMBER.

SPECIFICATION forming part of Letters Patent No. 319,443, dated June 9, 1885.

Application filed January 20, 1885. (No model.)

To all whom it may concern:

Be it known that I, ROBERT BOGARDUS, a citizen of the United States, residing in the city, county, and State of New York, have invented new and useful improvements in refrigerating cars or chambers which are used for the transportation or storing of fresh meats, provisions, dairy products, 850., and by which the confined atmosphere is rendered cold,more' dry,efflcacious, and uniform in temperature throughout, of which the following is a specification.

My improvements consistin several devices which are applicable to the general purpose of refrigeration-via, first, a tank or vessel to contain the refrigerating materials, so designed as to prevent the ice from becoming chocked; second, a system of fines or tubes arranged in connection with an ice tank or tanks in such a manner as to insure a more perfect circulation of air throughout the car or chamber and a consequent uniformity of temperature; third, a system of pipes that utilize the brine or pickle produced in the tanks for condensing and producing air free from moisture, and thus better adapted for preserving purposes; fourth, an icebreaker, icescreen,and tank-guard combined, to be placed over the opening or top of the tanks for the purposes the names imply. I attain these objects by the devices illustrated in the accompanying drawings, which form part of my specification, and in which each letter refers to the same parts throughout; thus, A will denote the interior of a refrigerating-chamber, (that is either portable or stationary C, an ice-tank; B, a receptacle and discharge-pipe for the liquid which forms in the ice-tank; D, flues; D,air-passagcs through flues; E, section of flue that is removable for inspection or repairs; F, cold air outlet or register; G, warm-air inlet or register; H, ice-breaker,

ice-screen,or tank-guard combined; 9, bars or grates; I, a pipe-connection between ice-tank and condensing and pickle-discharge pipe B; S, broken section in illustrations.

Figure 1 shows an interior sectional end view of a refrigerator car or chamber provided with my improved apparatus for insuring positive circulation and general distribu tion of the cold dried air. Fig. 2 shows a view in detail of the mechanical agencies I employ in cooling, drying, distributing, and circulating the air of a refrigerator-chamber. Fig. 3 gives a plan view of my improved icetank, showing the diverging side 3). Fig. 4: is a plan view of my ice-breaker, showing bars or grates 9.

To attain the first object,I construct a tank or vessel, with diverging side or sides b, so that the area of each cross-section of the tank will slightly increase from the top downward. This fornrof tank will prevent the ice from gorging or checking, which occurs in the tanks now in use, and from which cause great damage is liable to occur.

To attain the second object, I provide one or a series of air passages or flues, D, each similar in construction, as shown in Fig. 2, but independent in their action when arranged substantially as shown in Fig. 1. The fines D are constructed of wood, metal, paper, or other known suitable material. Each flue or tube D has two openings into the chamber A. The receiving-registers G of each flue are to come at different points on or near the ceiling of the chamber A, to receive the warm air. Each flue D continues along the ceiling to an assigned refrigerating tank or vessel, which it surrounds or faces against, utilizing its surface in the vertical portion of the flue D in passing downward to or near the floor, thencealong on, under, or near the floor to a point as signed for its discharge through registers F. By surrounding or directing the air against the refrigerating tank or vessel in a confined flue or tube it is chilled and condensed, which causes it to fall, and at the same time draw warm air from the chamber through the mouth or register G to take its place. The cold air by its altitude, density, and gravity forces the lower cold-air strata in advance out through the passage D in the flue or tube D, on, under, or over the floor to a point in A where it is most needed. I thus form a distinct continuous flow in flue D from its warm-air opening G to its cold air opening or discharge F, by which means warm moist air is taken from and dry cold air diffused equally in all parts of the chamber more easi1y,perfectly, quickly, and economically than heretofore.

The third object I accomplish by means of the tube or pipe 13, which is connected and combined with an ice tank or tanks by means of a pipe, I, leading into the tank 0, at or near the-bottom, thus making a water connection and discharge from the ice-tank Ointo the pipe B. I lead or extend the pipe B from the tanks through or along the air-passage D in the. direction of the cold-air register to a point determined by its usefulness. The pipe B must be laid and trapped so as to not permit the pickle it receives from the ice tank 0 to discharge until the pipe B is full. arrangement the warm pickle will only escape through the overflow at the extreme end or ends of the pipe B.

The fourth object I attain (as illustrated substantially in Fig. 4) by bars or grating g, of metal or wood protected by metal, so formed as to present an angular, round, triangular, or jagged surface to theice when laid thereon.

L This grating I rest or secure permanently over the opening or entrance of the tank or tanks. The spaces a limit the entrance to the tankof undesirably large lumps of ice. The ice is' placed on the bars 9, where itis pounded with a mallet or other known suitable utensil. The blows reacting against the bars break the ice into suitable proportions. By this means I prevent damage to the tanks by falling of large lumps into the tanks, or from damage occasioned by pounding to reduce these after entrance, or from serious damage to contents of chamber occasioned by insufficient refrigeration resulting from improper filling either by carelessness or ignorance.

My invention thus provides a simple, reliable, permanent utensil, and protection to the tank.

In my system of air-fines D, combined with pickle duct or pipe B, as arranged in eonnec tion with ice-tank 0, not any of the moisture from the melting ice can possibly enter the storage-chamber A, and the pickle, which is many degrees lower in temperature than the ice that produced it, being distributed longitudinally through the air-passage D, will condense the moisture from the air of the-chamber A, which is continually passing and re By this My system not only provides for a sectional distribution of the cold air in the chamber A, but also provides for obtaining the cold from one or more tanks or sections of the tank by inclosing in flue D such portions of the tanksurface as any particular flue may require to cool its allotted section.

I am aware that air-flues, pickle-pipes, and ice-tanks have been already employed in the process of refrigeration; but my improvements consist in anovel construction, arrangement, and combination of these appliances. Therefore,

Having fully described my invention, what I claim as novel, and wish to secure by Letters Patent, is

1. In a dry-air refrigerator, the ice-tank 0, having three vertical and one diverging side, I), as illustrated in Fig. 3, substantially as and for the purpose described.

2. In a dry-air refrigerator car or chamber, the flue D, when constructed, arranged, and combined with an ice-tank and chamber A, as and for the purposes substantially as illus trated and described. 7

3. In a dry-air refrigerator, the ice-tank 0, combined with flue D, all being constructed and arranged substantially as illustrated and described.

4. In a refrigerator, the ice breaker, screen, and guard H, when constructed as described, combined with an ice-tank, substantially as and for the purposes specified.

5. In a dry-air refrigerator car or chamber, the pickle duct or discharge pipe B, when combined with the flue D and ice-tank 0, substantially as illustrated and described.
